Irish digital marketing software company, Xtremepush, is set to double its workforce in Ireland and overseas to 140 over the next year.

It comes as the firm secured $33m in finance to further fuel its global expansion.

The new roles will be in software development, sales and marketing, finance and operations.

Headquartered in Dublin and launched in 2014 by Tommy Kearns and Dr Kevin Collins, the software as a service provider also has operations in the UK, Central and Eastern Europe and in New York state.

It develops services to enable companies to provide personalised, data-driven communications to customers across digital channels.

Among its clients are Bank of Ireland, AIB, McDonald's, RTE, daa and Paddy Power Betfair.

As part of the $33m fundraising, London based private equity firm, Grafton Capital, is to inject equity funding, with the balance coming from a refinanced debt facility.

"This investment validates and recognises the calibre of our technology, our people, and the ambitious global growth plans we have for the company," said Tommy Kearns, CEO and Co-Founder of Xtremepush.

"It will allow us to move ahead with our expansion in overseas markets, including North America, the Middle East and Asia."

"Xtremepush is now in hyper-growth mode. We want to scale quickly in all of these markets, both organically and through strategic acquisitions."

As part of the investment, Grafton Capital will take a minority stake in Xtremepush, with Edward Barroll Brown, Managing Partner of Grafton Capital, joining its board.

"We believe that Xtremepush is well positioned to grow as more and more businesses need to get smarter about how they engage their customers across multiple channels, whilst managing first party data and privacy requirements in a fast-changing digital marketing environment," he said.
